While building a RAID mode,
appears in the RAID Status screen. Clicking the
button aborts the RAID building process.
Note
RAID (Redundant Array of Independent Disks) helps you keep data safe in
case the system HDD is damaged.
Selecting RAID1 mode configures HDD1 and HDD2 as one array, and HDD3
and HDD4 as the other array. RAID1 uses 2 physical HDDs as 1 functional
HDD. For instance, configuring HDD1 and HDD2—while each is equipped with
a 500GB HDD—to RAID1 displays the system's functional HDD as one
500GB RAID. In RAID1 mode, no data is lost even if one of the two HDDs of a
RAID array is damaged.
Selecting RAID5 configures 4 HDDs to 1 RAID array. RAID5 uses 4 physical
HDDS as 3 functional HDDs. For instance, configuring HDD1, 2, 3, and 4—
while each one of them is equipped with a 500GB HDD—to RAID5 displays
the system's functional HDD as one 1.5TB RAID. In RAID5 mode, no data is
lost even if one of the four HDD is damaged.
RAID1 requires at least 2 HDDs to be equipped next to each other—HDD1
and HDD2, or HDD3 and HDD4—while RAID5 requires all 4 HDDs to be
equipped.
To configure a RAID mode, HDDs must be the same size. It is highly
